For you are all sons of God through faith in Christ Jesus.
In the Kingdom of God we are not subjects, but members of a royal family. Everyone in God's Kingdom is a prince or princess. There are no peasants nor middle class and no order of servants. In the Lord god's Kingdom, everyone is related to the King.
And because you are sons, God has sent forth the Spirit of His Son into your hearts, crying out, “Abba, Father!” Therefore you are no longer a slave but a son, and if a son, then an heir of God through Christ.
Galatians 3:26 Galatians 4:6-7
